there is a shuttle bus service called red vans that will bring you from lax to huntington. i looked up the prices ages ago so i cant remeber how much it was but it was pretty cheap. the more people that get the bus the cheaper it is. If you google them they have a website
just took the super shuttle from lax to huntington 38 dolars for the first person and 9 dolars extra for each extra person, dropped us right to the hotel door
